It is important to indicate at the outset that I do not intend to argue for more funding for soil conservation programs, but rather for more efficient use of the resources presently committed. Before we can go very far in evaluating the impacts of soil conservation spending changes, we need additional background on soil conservation programs. It is hoped that such information will tell us somet...
Soil and water conservation measures can impact hydrological cycle, but quantitative analysis of this impact is still difficult in a watershed scale. To assess the effect quantitatively, a three-dimensional finite-difference groundwater flow model (MODFLOW) with a surface runoff model-the Soil Conservation Service (SCS) were calibrated and applied based on the artificial rainfall experiments. T...
This Minor Field Study was carried out during November and December in 2011 in the Mount Elgon District in Western Kenya. The objective was to examine nine small-scale farming household ́s land use and socioeconomic situation when they have joined a nongovernmental organization (NGO) project, which specifically targets small-scale farming households to improve land use system and socioeconomic s...
the purpose of this study is to assess farmers’ attitude toward the soil conservation practices in the kushk-abad catchment basins in the province of khorasan razavi. a sample of 200 farmers was randomly selected from 1200 farmers living in kardeh catchment basin. data collection was done through a questionnaire that was administered in 2014. validity of the questionnaire was confirmed by a pan...
Soil conservation efforts in Indonesia since the Dutch colonial era have focused on introducing bench terraces—a costly soil conservation method for poor, upland farmers. Data from two villages in the Kerinci uplands of Sumatra illustrate that even with state underwriting of bench terrace construction, farmers across all economic strata still resist using this method. Why the state has not purs...
The Ethiopian highlands are affected by soil erosion resulting in the deterioration of properties. To reverse this, different and water conservation (SWC) measures were spatially practiced; however, effect SWC slope gradient on properties is not well studied area. Hence, this study was conducted to evaluate effects selected physicochemical Dawnt watershed, northwestern Ethiopia. treatments a co...
the modeling can provide a quantitative approach and consistency in the estimationsoil erosion and sediment yield by a wide range of conditions. in this study, the integration method of revised universal soil loss equation model, geographic information system and remote sensing techniques were used in order to identify the spatial distribution of soil erosion and sediment yield in the talar wat...
